Application filed March 16, 1908. Serial No. 421,295.

To all whom it may concern:

Be it known that I, ACHILL' WALTER BRAND, a citizen of the UnitedStates, residing at Boise, in the county of Ada, State of Idaho, haveinvented certain new and useful Improvements in Fuel-Consumers,Heat-Generators, and Heaters, of which thefollowing is a description,reference being had to the accompanying drawing and to the letters andfigures of reference marked thereon.

, My invention relates to new-and useful improvements in fuel consumersand heat generators, and has for its object to provide a fuel-consumingchamber with an arrangement of drafts whereby air is delivered to thefuel in a downward direction on top of said fuel. By this arrangement ofparts, I secure a device wherein-the heat is more quickly and evenlygenerated by a more complete combustion of the fuel, leaving nothing butone compact clinker.

A still further object of my invention is to provide a heater witha'water coil which encircles the combustion chamber and lies directly inthe path of the hot gases passing from said chamber. A further object ofmy invention is toprovide a combustion chamber which is closed at thebottom, and which is located in a surrounding drum or casing having adraft opening directly above the combustion chamber.

Further objects of my invention will in.

part be obvious, and in part be hereinafter more fully described.

In the drawing which shows by way of illustration one embodiment of myinvention,-Figure 1 is a front elevation of a heating device embodying-my improvements; Fig. 2 is a longitudinal sectional view of the same;Fig. 3 is a transverse view on the line 3'-3 of Fig. 2; Fig. 4 is adetail view'of the lid with the draft slide therein; Fig. 5 is a detailview and side elevation in plan, of the combustionchamber, showing ahandle for lifting the same; Fig. 6 is a sectional view showing amodified form of construction; and Fig. 7 is a detail in section,showing my drum with distributers.

A body portion 1 of my heater is preferably cylindrical in shape, andprovided at the bottom with a base portion 2 and a strengthening flange3. Legs 4, 4, are secured to the bottom of the casing, and, as shown inthe drawing, are of considerable length. Said legs are connected nearthe lower end by a supporting base or shelf 5. A strengthening rim orflange 6 is secured to the casing or drum near'its upper end. A lid 7,preferably of the same size as the casing or druin Tis used for closingthe upperend of said casing. Said lid is provided I with a projectinghooked-shaped arm 8, which engages a lug 9 carried by the casing ordrum 1. Said arm and lug are of the usual construction, so as to allowthe lid to be turned over, as shown in dotted lines in Fig. 1.

The lid 7 is provided with a slide 10, which is guided in suitableundercut ways formed in said lid as indicated in dotted lines in Fig. 4,so that the upper surface of said lid and said slide lie substantiallyin the same plane. The inner edge of the slide 10 is preferably curvedas at 11, so as to form a' slight opening through the lid when saidslide is in its closed position. Said slide is also provided with ahandle 12, for the purpose of operating the same. The upper surface oftheslide 10 and the lid is corrugated or grooved, as shown at 13 in Fig.4. The purpose of said corrugations will be hereinafter more fully de--scribed.

The heater is provided with a cover 13, which, as shown in the drawing,is curved in outline and provided with suitable openings 14. The innerportion 15 of said cover is also perforated, so as to allow currents ofair to pass down through the openings in the cover, when desired.

Within the casing or drum 1 is located the combustion chamber 16, which,as shown in Figs. 2 and 5, is in the form of a receptacle, having aclosed bottom. Said combustion chamber or receptacle, as shown in Fig.2, is provided with an opening 17 whereby said chamber may be liftedfrom the casing or drum. In Fig. 5 I have shown my combustion chamber asprovided with a handle 18 for lifting the same.

Suitable brackets 19, 19, are secured to the bottom portion 2 of thecasing, and provide suitable means for supporting the combustion chamber16, so that the same'is held in a central position in the casing ordrum.

1. A pipe 20 is secured to the bottom portion 2 of the casing, andextends directly 0 suitable sized drums, with two inside heat.

distributers 24 24 and 25 25 throwing all passing heat to the extremeperiphery.

of the drums. As shown in Fig. 7 said distributers each consist ofarectangular plate arranged as shown in said figure.

In some instances I may provide my heater with a water coil, which, asshown in Fig. 6, consists of a pipe 26, leading through the casing, andthen leading in coils 27 about the supporting bracket for the fuel potor combustion chamber, and then out through the side of the casing andupward, as shown at 28. A hinged cover 29 is secured to the end of thepipe 21, whereby access may be had thereto, for the purpose of cleaningthe flues.

. In operation, the fuel pot or combustion chamber is provided withsuitable fuel, and is then placed. in the casing or drum of the 30heater. After lighting said fuel, the slide 10 is slightly opened, whichallows a current 'of air to pass down through said opening on to thefuel in thecombustion chamber. As the fuel burns, the hot gases passingtherefrom lead up over the top of the fuel pot, and down around thesame, and into the flue or pipe 20, and thence through the pipes 21 and22 to the chimney. By this arrangement of parts, it will be seen thatthe 40 hot gases pass in' a downward direction from the fuel pot to thebottom of the heater, and as the heater ismounted on long legs, I securea very great length of. heat radiating surface. When the slide isclosed,

there is still a slight opening for sufficient draft to keep the. firefrom dying.

By corrugating the upper surface of the slide, cooking utensils may beplacedthereon without interfering with the draft. That is to say, theair currents will pass through the corrugations or grooves in the uppersurface of the lid and down through the opening formed between the endof thevslide and the lid. It will be obvious that said slide may bemoved to various positions, so as to regulate the draft for the fuel. Itwill be noted from Fig. 1, that when the cover is turned into theposition shown in .dotted lines, the same forms a rigid shelf, and

leaves the top of the stove free for cooking purposes, if desired.

The invention in its broader aspects is not limited to details ofconstruction herein shown, nor to any particular form of construction,as changes may be made therein directing a draft in a downward directionon the fuelin thevfuel pot, a pipe leading from the bottom portion ofsaid casing.
